/********************************************************
This function fabricates a new virtual page in which to display the requested product photo.
Pass parameter definitions:
Photo - String containing the filename (including directory) of the picture that you want to display.
Note that the string does not contain any context specifiers such as "../../". These are implemented
in the code below.
High - Height of the photo in pixels
Wide - Width of the photo in pixels
Calculations are performed in order to center the new window on the viewer's screen. The new window is then created,
and the picture is loaded into the document of this window along with a "close" button.
